K400 driver issues

Recently I upgraded to Windows 7 x64. I installed the setpoint drivers do I could disable 'tap to click' on the touchpad, because I frequently click by accident while typing and pressing the Enter key.

I have the keyboard paired with the Logitech M-UAS144 laser mouse, and both are recognized by setpoint. I have 3 problems:

1. K400 will slow down randomly, every 15-30 mins or so, as if there is 1-2 second latency for every input (connected to USB2 port on motherboard's extra usb2 pins; also tried the other usb2 ports). I must turn the K400 off then back on for a temporary fix.

2. When zooming with either the touchpad (Ctrl + two finger vertical movement) or mouse wheel, it makes the page massive or tiny, and no inbetween, making thse functions completely useless.

3. The middle mouse button on the laser mouse simply doesn't work.

These items are supposed to support Windows 7. I read that many others have problems with the new setpoint drivers, and unfortunately I don't have the old driver CD, and either way I don't have an optical drive (poeple in those forums were not successful in getting a solution from Logitech). The only solution is to use both items without the driver/software package, and lose all the advertised functions.

I have been buying Logitech (exclusively) for my mice / keyboards / remotes / and speakers, but in the last few years there has been an obvious decrease in the quality of your products. After replacing my Z2300 speakers with the Z623 I was originally pleased. Just afer 1 year, the power button got 'loose' with regular use, and I treat it properly. The speakers would cut in and out by the vibrations of the bass. I replaced the system with another Z623, and not even 6 months later, whenever I turn the volume up or down with the control knob, there is a loud crunch on the base and crackles on the mids.

I'll be honest. Logitech has been my favorite computer related company, ahead of Asus, Samsung, Creative, Altec, and that means a lot. Next time I'm looking for any of the items listed above, I will probably be trying out one your competitors, I am truly sorry to say. You had such rock-solid products and incredible value for more than a decade of purchases.

I sincerely hope this message helps you turn things back in the right direction,

I'm sorry to hear your experience in regards to Setpoint software. As I understand, you are currently using the keyboard as a generic plug-and-play device as of the moment. Relative to this, you have also stopped using the LS1 Laser Mouse (M-UAS144) due to some functionality problems.

Please try to check if installing Setpoint v. 6.52 will correct this issue. I believe some features has been updated on this version. Feel free to post back for the results.
